Freon is a coolant made by DuPont that is synonymous with air conditioner refrigerant. The coolant is common in older air conditioning systems, such as models produced before 2010. However, most modern aircon in Singapore now use eco-friendly refrigerants. But, regardless of the type, a low refrigerant charge can cause your air conditioner to struggle to cool a room.
Some brands may manufacture error codes to signify low refrigerant charge, but there are multiple ways to tell if your air conditioning unit needs a top-up.
Signs of An AC Running on Low Freon
Sign #1: AC System Blowing Hot Air
The most common sign of an air conditioner malfunction that we have found among our clients in Singapore is the unit blowing warm air instead of cool air. Air conditioners that blow room temperature air are not sufficiently cooling the air flowing through the system and are almost always due to low refrigerant levels in the unit.
Sign #2: Air Conditioner Leaking Water
If you notice water pooling around your air conditioner, it could be a sign of low Freon levels. In Singapore’s humid climate, condensation naturally forms on the evaporator coil. However, when there isn’t enough Freon, the coil may freeze and later melt excessively, causing leaks. Some of our clients in Singapore have experienced this issue, especially in older AC units that haven't been regularly maintained.
Sign #3: Ice Build-Up on the Refrigerant Line
Another clear sign of low Freon is ice forming on the refrigerant line or the evaporator coil. This happens because reduced refrigerant levels cause the coil to become too cold, leading to ice accumulation. Over time, this can strain your AC unit and cause further damage which will reduce its efficiency over time.
Sign #4: Humming, Hissing, or Bubbling Noise
A loud, dry humming noise indicates that your air conditioning system is working harder to keep the air in your room cool. This is one of the symptoms of low refrigerant, while a hissing noise indicates a leak in the refrigerant lines. If the leak is a big one, then the aircon may also make a bubbling noise as the coolant escapes the coils.
Sign #5: High Electricity Bills
High electricity charges may also be caused by low refrigerant levels as your aircon unit works harder to cool your room, using up more energy to function without adequate refrigerant levels. High electricity bills may indicate several issues with your air conditioner, and low refrigerant is one of them.
What to Do Next?
When you suspect a Freon leak in your air conditioner, immediate intervention is a must. This is important if you want to keep your aircon working properly and at the same time protect your health. Here’s why timely intervention is crucial when dealing with a Freon leak:
- Prevent System Damage: Running an AC with low Freon can overwork the compressor, which can eventually lead to costly repairs or even a complete system breakdown.
- Ensure Efficient Cooling: In Singapore's hot weather, an underperforming AC can make indoor spaces uncomfortable and increase energy bills.
- Protecting Health: Leaking Freon can pose health risks, such as respiratory issues and dizziness. It’s important to address leaks immediately to protect you and your loved ones health.
Freon is a highly hazardous substance. It is not something a regular homeowner should be handling without proper equipment, protective gear, and expertise. Our Luce Aircon technicians are well-versed in the dangers and proper handling of Freon, so trust in us to do the repairs for you. We'll find that leak, and fix it too!
Maintain Your Cool
Freon, refrigerant, Puron, or other coolants are essential parts of any cooling system - arguably the most important player in your unit as it is responsible for keeping the warmth out, and the cool in.
If you notice poor cooling performance or error codes indicating low refrigerant, it’s time to consult a professional. At Luce, we’re equipped to handle refrigerant-related issues across various aircon brands, ensuring your unit runs smoothly in Singapore’s tropical heat.
